The ntp collector has always been a source of confusion and problems.
The data it produces is more of a blackbox probe against an NTP server.
The time sync / offset data produced is not what users expect.
Mark this collector as deprecated to be removed in v2.0.0

With `--runtime.gomaxprocs=0`, the GOMAXPROXS value will default to the
number of logical CPUs. In this case, it is more useful to log the
actual value than the value set by the user via the command-line.

NOTE: This changes the Go runtime "GOMAXPROCS" to 1. This is done to limit the
concurrency of the exporter to 1 CPU thread at a time in order to avoid a
race condition problem in the Linux kernel (#2500) and parallel IO issues
on nodes with high numbers of CPUs/CPU threads (#1880).
* [CHANGE] Default GOMAXPROCS to 1 #2530
* [FEATURE] Add multiple listeners and systemd socket listener activation #2393

Avoid running on all CPUs by limiting the Go runtime to one CPU by
default. Avoids having Go routines schedule on every CPU, driving up the
visible run queue length on high CPU count systems.
This also helps workaround a kernel deadlock issue with reading from
sysfs concurrently.
